WUH722626ALE6L4

The WUH722626ALE6L4 is a 3.5-inch data-center hard drive in Western Digital’s Ultrastar DC HC590 family, an 11-disk CMR platform listed on the manufacturer’s SATA 6 Gb/s interface. The Ultrastar DC HC590 data sheet gives this configuration a formatted capacity of 26TB, 7200 RPM spindle speed, a 512 MB data buffer, workload handling of up to 550TB/year, a projected MTBF of 2.5M hours, 5-year limited warranty, and an operating temperature of 5° to 60°. The manufacturer’s product page prints its order-code list verbatim as “26TB, SATA, SE: 0F65672”, and shows the model number WUH722626ALE6L4 for this configuration; the matching Western Digital part number is 0F65672, offered as Base (SE), no encryption. Sector format is Advanced Format (4Kn: 4096, 512e: 512).

Model and part number

This page is the customer-orderable model number WUH722626ALE6L4; the same drive is also carried in Western Digital’s inventory systems under the part number 0F65672. Both identify this one 26TB SATA 6 Gb/s HC590 unit and are cross-referenced here so a quote can be matched by either code.

What this page does and does not state

The HC590 data sheet specifies the family in four columns — 24TB and 26TB, each over SATA and SAS — and does not enumerate individual order codes in its tables; the concrete model and part numbers above are taken from the manufacturer’s product page, which lists them under Model Numbers. The spindle speed, buffer, recording technology, workload, reliability and warranty figures are shared across that table; what is asserted only for this configuration is its formatted capacity (26TB), interface (SATA 6 Gb/s), model number, part number and data-security option. Other row-dependent columns (areal density, sustained transfer rate, power figures) are not restated here. The MTBF is given by the manufacturer as a projected estimate, not a measured value. The manufacturer publishes no temperature-grade/qualification standard or lifecycle statement for this family, so none is claimed here.

Data source

Shared figures are taken from the manufacturer data sheet Ultrastar DC HC590 Data Sheet (©2024 Western Digital Corporation), md5 a7c9c89e740305d4f74727ebdd39f46c; the order-code list is taken from the manufacturer’s product page. No public datasheet link is claimed and the external reference points to the manufacturer product page.
